Invoking the action from HTML

To include active help links in your documentation, you must first declare the use of the supporting JavaScript code. The live help JavaScript is located in the org.eclipse.help plug-in.  You refer to it using the help system's crossplug-in referencing technique. This script reference should be placed in the HEAD section of your HTML:

<script language="JavaScript" src="PLUGINS_ROOT/org.eclipse.help/livehelp.js"> </script>

In the body of your documentation, you invoke the liveAction script.  

<a href='javascript:liveAction(
	"org.eclipse.platform.doc.isv", 
	"org.eclipse.platform.doc.isv.activeHelp.ActiveHelpOpenDialogAction",
	"")'>Click here for a Message.</a>

The parameters for liveAction are 

• the ID of the plug-in that contains the action
• the name of the class that implements the action
• the String that will be passed to the live help action using setInitializationString.  We don't need to pass any information from the HTML page, so we just pass an empty string.
